h(t) = -16t2 + 704t
the maximum will occur at the axis of symmetry.
we can find the axis of symmetry at
h = -b/2a
where at^2 +bt+c
so a = -16 and b = 704
h = -704/(2*-16)
i am assuming the $100 dollars was the initial purchase price.
if that is true we subtract from the $640 total payed:
640 - 100 = $540 dollars.
next we divide the 540 by the monthly $30 dollar rate:
540 / 30 = 18
check our work:
18 months @ 30/month = 540 + 100 dollar down payment = 640.
i don't know what the scenarios are but an exponential decay is when something decreases over time. on a graph its a curved line on the graph.
you would take 1,959 and divide it by 6.3. the answer of that will be added to 1,959. and that's how i got the answer good luck! and i hope that this .
also quick note 2269.95 is how much is made in a month! : )
at 5 and has a slope of -3?
